ParaShield 1224

User’s Manual

ParaShield 1224 is designed to provide a local power solution for cable

telephony, wireless local loop (WLL), and fiber to the home (FTTH)

broadband equipment.

IMPORTANT SAFETY WARNINGS

This manual contains important instru ctions regarding the installation and
operation of this device. Read this manual thoroughly before attempting to
unpack, install or operate this device

CAUTION! The battery can energize hazardous live parts inside even

when the AC input power is disconnected.

CAUTION! To reduce the risk of electric shock, do not remove the cover,

except to service the battery. No user serviceable parts inside, except for the

battery.

CAUTION! To avoid electric shock, turn off the unit and unplug it from the

AC power source before servicing the battery or installing your equipment.

(SAVE THESE INSTRUCTIONS)

INSTALLATION

(QUALIFIED SERVICE PERSONNEL ONLY)

Please read this manual before installing this DC UPS as it provides important

information that should be followed during the installation and repair of the DC

UPS:

1.) The ParaShield 1224 is intended to be installed in a temperature controlled

environment that is free of conductive contaminants. Select a location which

will provide good air circulation for the DC UPS at all times. Avoid locations

near heating devices, water or excessive humidity, or where the DC UPS is

exposed to direct sunlight. Route power cords so they cannot be walked on

or damaged.

2.) Remove the cover.

3.) Remove the battery.

4.) The wall mount screws must be the appropriate size for total weight of the

UPS and the mounting structural material.

5.) Connect the battery negative (Black) wire to the battery negative terminal.

6.) Connect the battery positive (Red) wire to the battery positive terminal.

7.) Re-install the battery into the ca se.

8.) Connect the output wires and connector to the DC UPS.

9.) Connect the Communications Signal wires to the DC UPS.

10.) Re-install the cover.

11.) See the section “Operation” for the startup procedure.

OPERATION

1.) Plug the DC UPS power cord into the AC inlet on the DC UPS.

2.) Plug the DC UPS power cord into the wall outlet.

3.) Turn on the connected equipment.

4.) The DC UPS is ready for normal operation.

The DC UPS charges the battery when it is connected to utility

power. It is recommended that the battery charge for minimum of

18 hours before use. The DC UPS may be used immediately,

however, the “On Battery“ runtime may be less than normally

expected.

BATTERY REPLACEMENT

(QUALIFIED SERVICE PERSONNEL ONLY)

This DC UPS has a hot-swappable battery. Hot-swappable battery means

that the battery can be replaced without powering down the whole DC UPS

system.

If there is a power interruption while replacing the hot-swappable

battery, with the DC UPS on, the load will not be backed up.

CAUTION!

to the skin and eyes and may be toxic.

CAUTION!

system can still present a risk of electrical shock. The current capability of a

battery is sufficient to burn wire or tools very rapidly, producing molten metal.

Observe these precautions when replacing batteries:

1.) Remove watches, rings, or other metal objects.

2.) Use hand tools with insulated handles.

3.) Wear protective eye gear (goggles), rubber gloves and boots.

4.) Do not lay tools or other metal parts on the top of the batteries.

5.) Disconnect the charging source before connecting or d isconnecting the

battery terminals.

6.) Determine if the battery is inadvertently grounded. If the battery is,

remove the source of the grounding. Contact with any part of a grounded

battery can result in an electrical shock. The likelihood of such shock will be

reduced, if such grounds are removed during installation and maintenance.

Step 4. Connect the black cable to the battery negative terminal on the new

battery.

Step 5. Connect the red cable to the battery positive terminal on the new

battery.

Step 6. Install the new battery into the battery compartment.

Step 7. Tighten the battery stripe to secure the battery.

Step 8. Re-install the battery cover.

Step 9. The DC UPS is ready for normal operation.

Step 10. Dispose of the old battery properly.

Do not open or mutilate batteries. Released electrolyte is harmful

Do not dispose of batteries in a fire. The batteries may

explode. The batteries in this UPS are recyclable.

Dispose of the batteries properly. The batteries contain

lead and pose a hazard to the environment and human

health if not disposed of properly. Refer to local codes

for proper disposal requirements or return the battery to

MINUTEMAN in the packing material for the new

battery.

Although battery system voltages are only 12VDC the battery

○ Buzzer On/Off Switch: The default position of the buzzer switch is OFF. If

you want to enable this function, there is a button inside the hole, please

insert a paper clip or small pointed object into the hole and press the button.

In case of utility failure (on battery), it will emit a long beep. In case of low

battery, it will emit a short beep.

Communication Signals

The communication signals of this unit are isolated from the internal circuitry

via open collector Opto-coupled transistors. The connection “SIG RTN”

(Signal Return) is a common return point for all communication signals. In

the typical application, the attached equipment digital ground connects to

Signal Return, and pull-up resistors turn the open collector signals into logic

levels.

particular insta llation. If this equipm ent does cause harmf ul interference to radio or television re ception, which can be determined by turning the equipment off and on, the user is

encouraged to try to correct the interference by one or more of the following measures: (1) Reorient or relocate the receiving antenna. (2) Increase the separation between the

equipment and receive r. (3) Connect the equipm ent into an outlet on a circuit different from that to whic h the receiver is connected. (4) Consult the dealer or an experienced radio/TV

technician for help. Any special accessories needed for compliance must be specified in the instruction.

CAUTION: A shielded-type power cord is required in order to meet FCC emission limits and to prevent interference to the nearby radio and television receptio n. It is essent ial that

only the supplied power cord be used. Use only shielded cables to connect I/O devices to this equipment.

CAUTION: Any changes or modifications not expressly approved by MINUTEMAN UPS could void the authority granted by the FCC to operate this equipment. For more information,
